Frame Complete

Today I received and assembled my v4 JAG frame.

This weekend it will be on display at Maker Faire in the San Mateo Fair Grounds. The Bay Area R2 Builders will be exhibiting 2 (Chris James' and Gerard's) R2-D2's. My frame will be there to show the early steps to getting started.

I am currently waiting on my 300mm Dome, Steel Center Foot, PSI's and Rockler Bearing.

First Paint Tests

Today I started testing the paint that I picked up over the weekend. It comes in three cans. A base coat, a color coat and a clear top coat.

To test these out, I cut apart an aluminum can and started spraying. After adding the minimum number of secondary coats and no clear coat, this is what my torn up can looks like:

Single overhead light and flash (above)


Light from all sides and flash. Shows the full range of color shift.(above)


Light from all sides, no flash and extreme angle (above)

The pics with the multiple light sources resemble what the paint looks like outside. I still need to test it a little more in areas with a lot of overhead florescent lights to be sure that it will look good on a convention floor.

Note: I did the base coat in my garage last night and the limited lighting was tricky on the eyes. The large piece of aluminum was not well covered with the base paint and it shows (at least to me).

So, for anyone reading this let me know what you think of the color scheme. If you know anything about lighting and this sort of paint, give me feedback on the pitfalls or benefits of going this route.

Peace.

The Road Less Traveled

Its been a while since I started on this process and I have learned a few things. If you don't have access to a machine shop, building a solid droid will be a long and expensive process.

As a result, I have become a parts collector. As people with certain skills pump out a set of parts I need, I have to get in on it or wait a long time until the event occurs again (like waiting for Haley's Comet as far as I'm concerned).

Being a parts collector is not too bad, but keeping the available cash to purchase things when they are available is the tough part. Most people are like me, living on the edge. With a clergy salary that only pays the mortgage (literally) and living off of the second income of my wife/secretary, I have turned to collecting recyclables from everyone I can so that I can redeem them for droid money.

Its a bit ironic I guess, recycling all that aluminum so that I can purchase more aluminum. My friends hear me constantly say, "If you throw that can away, you are stealing from R2! Hes crippled and needs feet you barbarian!"

So on to the actual meaning of my post title...

I have decided that I don't want to make just another R2-D2. There are several of those out there (at least 2 completed here in the SF Bay). I want to do a custom job, providing the paint that I want comes out correctly when applied.

My wife had the idea of using color change auto paint to replace just the blue parts of R2. I wasn't sure what it would take to do that but found that the paint was readily available at Kragen Auto Parts. (Photoshopped concept to the left)

Providing it all works out and he looks good that way, I figured on calling him R2-XS since his colorful bling looks to be a little bit in excess.

It is also worth noting here that I have started using the Droid Cost Summary sheet. I uploaded it to Google Documents so that I can share it with my wife.

I went through and populated it with all of the parts I can name and added URLs or names of people where the parts can be purchased. It helped me create a comprehensive checklist as well as organize all of the URLs to various hobby stores that were beginning to clutter my favorites list.

My first R2

On a nostalgic note, my dreams of building an R2 were first realised back when I was 8 or 9 years old. Our family visited the Estes Rocket factory in Colorado and I came away with an R2 Rocket kit that I put together and launched.

I tried to locate one today but they don't really exist any more. I think the basic reason for it is that R2 doesn't fly well when launched from a center rocket. Here is someone else's YouTube version of what happened to mine.



After mine hit the ground the legs broke off and the chute was burned up due to engineering problems.

Back to the progress of building a life size droid...

I have been reading about 12v vs 24v systems and looking at wiring diagrams and all of that stuff. Its a bit difficult building a context for some of what I am looking at since I have never done any of this before. It can be overwhelming at times.

Also, I have been struggling over the idea of people purchasing parts, vs. making them yourself. Obviously if your budget is severely limited (like mine) then you cant afford to purchase thousands of dollars in aluminum parts, which may force you to build your own out of other materials.

The result is that you sacrifice realism and a certain amount of quality for cost effectiveness. On the other hand, you have the pride of crafting your own droid, rather than just building one (as one would a model plane).

I know that I will have to purchase some parts that I just can't make look good enough, but it may take me years to nickel and dime them as part runs come out. I'm also trying to find ways to machine some of my own aluminum parts so that I can have the quality without the cost, but my machining resources are limited and sketchy at best.

So in the mean time, as I continue to read and plan, I have also designated the family change box as the "Droid Fund". When I cleared it out last time it had almost enough for my Dome down payment.

In the beginning...

Back before Episode III I started prop building and costuming. I ended up focused on Light sabers and leather working for Jedi Belts, all of which landed me in the Rebel Legion.

Fast forward several years I'm in a new town and needing new challenges. So I went to San Francisco's WonderCon hoping to make some connections with Star Wars geeks of like mind, which is where I was introduced to the R2 Builders.

I have always loved R2-D2 and like every kid of the 70's dreamed of having one of my own. So when I saw the R2 units driving around WonderCon I had to stop and talk with the builders. It was there I met Chris James and found out that he was virtually a neighbor.

After meeting him and joining the R2 Builders Group at Yahoo, I decided that it was time for me to take on new challenges and give this a go. So, I started reading the boards as much as possible. I took the advice of starting a folder of print outs and images and I took the leap of faith to order a dome (since there was a run happening with a few extras available).

I know that most people advise months of research before starting on this project. I didn't fully take that advice for several reasons:

1. I'm basically adult ADD. I cant process that much technical crap without starting somewhere and just getting things done.
2. The information is overwhelming and I just needed to start something in order to get my head around things.
3. If I took too much time theorizing about things then I would just end up being a talker rather than being a doer.

I have taken the leap of faith and started this thing off. Let me say off hand that I could not have taken this leap of faith without the support of family. Many people have spouses and children with varying needs and ideas about the coolness (or lack) of Star Wars replica building.

In my situation, I have a wife that is highly supportive and looks forward to having an R2 that we can be proud of. My kids think Star Wars is the coolest thing in the world and are frustrated that they aren't old enough to be Rebel Legion members themselves. :) What that means is that this is at least starting off as a family project. The beauty of all that is that my wife approves of spending money on parts and my family won't feel like they have been widowed by R2.

Like me you may be wanting to start a droid, but you are worried about taking it on because you have "no skills". As I start this off, I want to let you know about me and my skills that I have coming into the project...

MY SKILLS (Or lack of)

I have worked on prop building in a few areas:
1. Taking Bondo/Resin parts and modifying them with a dremel tool, prepping and painting them to look real.
2. Dremeling aluminum parts to create light saber pieces.
3. Taping aluminum with threads (for blade length adjusters that hold in removable blades)
4. Soldering minor electrical parts together for lighting and power sources. I have never created any special kind of circuit and have no idea what most of the electrical components on a board are called (much less how they function).
5. I have done some mechanical work on cars and have a basic understanding of tools and gears.
6. I spent time in Wood Shop, Auto Shop and Welding Shop in school, but never completed a semester in either. I have also spent time in Machine shops watching other people work, but have no skills in the craft.

WHERE I STARTED...

I began by looking at an old version of a frame that looked like I could cut by hand. I started creating a styrene prototype with basic styrene boards from Office Depot. It helped me see some details missing in the frame and made me think about what I would need in order to accomplish the droid that I want to build.

Here are the current specs of the droid that I would like to create. I'm sure that later I will look back and realise how much I failed to take into account, but never the less, here it is:

1. Authentic looking droid - I don't want to have to paint wood or resin parts to look aluminum. If its a raw aluminum part, I want it to be made of aluminum.
2. Hatches in the dome and in the body to open and close. In the future maybe those can be automated.
3. Periscope, fire extinguisher and life form scanner functions in the dome.
4. I would like to explore sound and motion sensors in the dome to see if some automation is possible. As well as the possibility of web cam functions in the radar eye.
5. Radio controlled with the possibility of the feet becoming 2-3-2 in the future.
6. The Droid should be sound enabled so that he sounds like R2 and has options for playing a range of beeps and whistles.

So, there it is. I am waiting for my dome (still paying for it) and searching for framing options.
I'm also clearing a work space in my garage so that I will be able to work freely. In the meantime, I keep reading the boards and blogs to find out what I don't know.

Peace.
